Answer: 25.9</h3>
========================================
x = length of AB
The parallel bases of the trapezoid can be added up, and divided over 2, to get the length of the midsegment. The midsegment is the line that cuts the nonparallel sides (or legs) of the trapezoid in half. The midsegment is parallel to the bases.
So,
(AB+DC)/2 = MN
(x+11.5)/2 = 18.7
x+11.5 = 2*18.7
x+11.5 = 37.4
x= 37.4-11.5
x = 25.9
AB = 25.9
Answer:
The increase in temperature is 
Step-by-step explanation:
we know that
The formula to calculate the rate or slope between two points is equal to

we have

Substitute the values


therefore
The increase in temperature is 
Answer: The answer is the picture shown below
Step-by-step explanation:
To do this you will need to make a coordinate plane about 20 up and 20 down. So there is a formula that is y=mx+b which is called the slope intercept form and as you can see the problem given to you was already given in this formula. The variable m in the equation is the slope and slope is also known as rise (which basically means go up if positive and down if negative) over run (which is right if positive and left if negative) and as you can see in the equation the number 4/5 is the variable m. Since slope is rise over run 4 would be the rise and 5 would be the run, so you would go up 4 and right 5 because they are both positive. Now there is another variable that is b which would be the -1. In slope intercept formula b is the y intercept so -1 is where the line would cross the y axis. Now that you know all the parts to the slope you can put it together giving you the answer.
To get this answer you would have to have a pace calculator!
